ow when lowering the main light
post and retracting the horizontal mast arm. There are TWO Models of Actuator, that
could be potentially installed on your unit. They have different take-down procedures.
Review the different models below before take-down.
WARNER LINEAR / THOMSON ACTUATOR
Tools Required: 3/16” Allen wrench, 1/4” drive ratchet with an extension or, to save
time, a drill with at least an 8” extension.
Remove silver access cap on the actuator motor housing using a 3/16” Allen wrench.
Using the 1/4” drive extension at least 8” in length, lower the main light post until it
reaches the holding bracket (to prevent stripping, set the drill to a low clutch setting).
If required, repeat the process for the horizontal mast arm to retract the light housing
extension.
PROGRESSIVE AUTOMATION ACTUATOR:
Tools Required: T 30 Torx bit, 6mm hex bit with an extension or, to save time, a drill with at
least an 8” extension.
Use the T-30 Torx bit to remove silver access cap on the actuator motor housing. Using the
6mm hex bit and drive extension, turning counterclockwise, lower the main light post until
it reaches the holding bracket (to prevent stripping use the drill set to “screw” mode or the
highest clutch setting). If required, repeat the process for the horizontal mast arm to retract
the light housing extension.
